从实际了解可知精密配电柜的特点

(1)精良的制作工艺和漂亮的外观,以与现代机房的可靠性和环境要求协调;

(2)完善的监测功能,如:电压、电流、有功功率、无功功率、有功电度、无功电度、谐波量、开关状态、支路电量等,以满足整体机房监控系统的要求;

(3)输出支路的开关具有热插拔和调相功能,以方便运行中开关的更换和调整三相负载平衡;

(4可加装隔离变压器(或K因数变压器),以实现电气隔离和降低零-地电压。

2   精密列头柜与配电柜的区别

精密配电柜已在机房中被广泛使用,但国标对此并没有定义,即没有相关制作规范,现实产品也各异。与其相似的列头柜也在机房中广泛使用,国标对此有定义,在《电子信息系统机房设计规范》中:“2.0.18列头柜(arraycabinet)为成行排列或按功能区划分的机柜提供网络布线传输服务或配电管理的设备,一般位于一列机柜的端头。”由于两者在电气位置和物理位置上不同,功能上也不完全相同,不能混为一谈。图1和图2是两种典型的机房电气系统结构图。

图1  中小型机房供电系统

图1是用于中小型机房的情况,机柜数量较少;UPS系统输出通过精密配电柜直接向机柜供电;对于单电源负载要通过STS切换供电,STS容量较大,不能放在精密配电柜中。

图2  大型机房供电系统

图2是大型机房的情况,机柜数量很多,机柜常按列放置;其中也有UPS的输出配电柜,但它一般选用容量较大的优质低压配电柜,配电柜输出支路开关不具备热插拔和调相的功能,监测的电量也不是很多。对于此种情况,UPS系统输出电量先经输出配电柜粗分配,再由列头柜细分到各机柜;对于单电源负载要通过STS切换供电,STS容量较小,可放在列头柜中。

为了清晰认识这两种设备,笔者给出列头柜和精密配电柜的相同点和不同点。

(1)相同点:

①相比普通配电柜,柜体制作和布线工艺都比较精良;

②都具有比较完善的电量监测功能并提供RS232、RS485通信接口;

③输出支路开关都需设置热插拔和调相功能;
